App Download
App Download is the “smart” content type – it can recognize the type of device scanning it and automatically deliver a mobile experience optimized for that platform. If you’re publishing a mobile app, you can use App Download with your recognition technologies to automatically send customers to the right download for their phone, so they don’t have to search for it in a mobile marketplace. App Download works equally well with Tag barcodes, QR Codes, and NFC touchpoints. Instead of multiple Tags, for example, pointing to different URLs, a single App Download Tag works for all supported smartphones. (You can also specify a default URL for other platforms.)

Creating Platform-Specific URLs
To implement the App Download feature, you can use the URLs provided by mobile marketplaces to link to your application and direct users to the right location. Refer to the specific platform’s marketplace to learn how to create URLs that point to your application:
Example: Creating Links for Windows Phone Marketplace Links to Windows Phone Marketplace items begin with the base URL, http://social.zune.net/redirect. Query string parameters are required to indicate a specific item and the content type of the item. Optional parameters can be used to specify a requested client application for displaying the item, an action to be taken by the client application, and the source of the link. Here’s an example link: http://social.zune.net/redirect?type=phoneApp&id=c14e93aa-27d7-df11-a844-00237de2db9e
The following table lists the parameters that can be used to create a link to an item in Windows Phone Marketplace:
| Parameter | Required | Value |
| type | Required | In the current release, the only supported value is “phoneApp,” indicating a phone application. |
| id | Required | The ID assigned to the item by Windows Phone Marketplace. |
| source | Optional | The source of the request. This string is only used for reporting. |
Creating App Download Tag barcodes, QR Codes or NFC URLs
In Tag Manager, enter the target URL you’ve generated for each supported platform, as in the examples below. For unsupported platforms, enter the default URL.
| Default URL: | www.bing.com |
| URL for Windows Phone 7: | http://social.zune.net/redirect?type=phoneApp&id=c14e93aa-27d7-df11-a844-00237de2db9 |
| URL for iOS : | http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=294409923&mt=8 |
| URL for Android: | market://details?id=com.rovio.angrybirds |
| URL for Blackberry: | http://appworld.blackberry.com/webstore/content/680 |
Note: NFC URLs work with the Android platform, so they should only direct to the Android Market.
